If you're American, you'll probably do better than we did. Our waitress was new (it was her first day) and I overheard her telling another customer that while she was okay at speaking French and living in Paris, she hadn't quite got a handle on waiting tables. That was evident by the level of service we received, only being Brits.
Nevertheless, the food was good, and the drinks reasonably priced (by Parisian standards). This is the 25th Hard Rock I've visted over the years and, barring substandard witing staff, you know what you're going to get at a Hard Rock. Good food, clean restaurant and good music.
Oh, and a cute Parisian Teddy Bear for the collection!
